1. A 3D printer, such as the Fab at Home, can print accurate silicone anatomical models much more quickly than conventional methods.
2. Why is the error larger for the vertical axis, even though the resolution is smaller? Is this an effect of gravity?
3. A presentation could be given on the accuracy and efficiency of different fabrication methods and printing materials.
4. If the potential for the silicone to drip before it dries can affect accuracy, why not print a structure out of plastic to support the silicone (using the same method as used to support horizontal structures)?

1.) A Fab@Home 3D printer was used to create an accurate silicone replica of a human aortic stem.
2.) Re there any other types of polymers that are compatible with the Fab@Home which might respond better to fabrication other than common silicone.
3.) A presentation could be given on the applications of such a model as opposed to conventional methods.
4.) Is it really cost effective and worth the decrease in functionality to produce these models using fab@home and not the conventional methods?

1. Fab@Home was used to make a silicone aortic system, which was then dipped in silicone to provide more accurate mechanical properties (compared to porcine heart).
2. They briefly mention that any viscous material used for building will present problems. How did they get the epitrochoid portion to not collapse while the silicone was still very viscous? How viscous is common silicone? Can the nozzle dispense different diameter streams of silicone for different desired thicknesses?
3. Mechanical properties of silicone prototypes created by different methods (Fab@Home, casting method)
4. I wonder what other materials you could use with the Fab@Home. I've read about organ printing; is it similar to this?

1. A model of a human aortic root can be made out of silicone using Fab@Home which is much faster than previous methods.
2. Is it really as easy to adjust the mechanical properties as the authors imply? Just mix together 2 or 3 types of silicone?
3. Present the information in table 1 for the current fabrication methods to offer a better comparison.

1. A faster method to fabricating a model of the human aortic root has been developed using dipped silicon.
2. Are the values of the aortic root radii consistent in all humans or are they seeking to make more individualized aortic root models.
3. Medical applications of the model root.

1. You can use fab@home to create a replica of an aortic root to practice surgery on.
2. I understand that it's a method for rapid prototyping, but wouldn't it be easier, faster and more accurate to just use a mold?
3. Other uses for fab@home

1. The fab@home can be used to create models of organ parts that can be useful in surgical practice and education.
2. If multiple copies of the same aortic root are needed, this method is not very scalable. It is very good though if different dimensions are needed each time.
3. The potential and present impact of the personal fabrication movement on science and medicine.

1. Fab@Home can be used to make a real-sized model of the human aortic root.
2. Can Fab@Home fabricate implantable devices such as stents from bio-compatible substances?
Why isn't the surface of the model smooth?
If industry-grade silicone is better, why didn't the authors use it?
3. Production of these models using industry-grade silicone.

1. A 3D printers shockingly do what their name implies.
2. Is this a vanity publication? Does the method of printing produce any anisotropy of the materials properties, generally?
3. different 3D printer brands
Lindsay Chatfield
ReplyDeleteKalejs
1. The Fab@Home is a three-dimensional printer that can produce a life-size model of the human aortic root more quickly than the traditional casting method. Such a model could be used for educational purposes as well as surgery planning.
2. So, did they need to use a second deposition tool to print supporting material for the "epitrochoid" part of the model? In the little Video 2 picture, it looks like they did not. Also, do they have a way to tell beforehand if they need a supporting material? Or do they just kind of wait and see what happens?
3. Other applications of the Fab@Home.
4. Alex, when are you making us cupcakes?

1. A Fab@Home system was used to print a 3D model of a human aortic root.
2. Why was silicon chosen as the material of choice? What are other alternatives that better mimic aortic materials? Also, what is the advantage of the Fab@Home over "previous casting methods", exclusing time.
3. How rigid is the actual aorta? How close to it is the coated model? Apresentation on various materials to simuate aortic tissue might be better.

1. Fab@Home 3D printer was used to make a model of an aortic root.
2. If the model needed to be dip-coated, is the improvement in production time still. significantly better? Does the "visible layered structure" affect efficiency?
3. A presentation on the different applications of the Fab@Home in general.
Samat Kabani

1. By using Fab@Home as a 3D printer, a replica of an aortic root was modeled.
2. What is the smallest syringe diameter tip one can use while not increasing production time beyond conventional molding time?
3. Use of Fab@Home at Sybbure
This paper talks about an easy and cost effective way of developing silicone replicas of body parts using a program called Fab@Home. My questions are:
ReplyDelete1) What is the degree of complexity can Fab@Home recreate? Can it create whole organs? A complex organ like the heart or kidney?
2) What are the possible applications for this innovation?
3? Can it be used for applications other then this one?
1. Fab@Home print human aortic root with silicon.
ReplyDelete2. What other ways can the excess silicon can be control beside making the tip of the pipette smaller?
3. We can do this in our lab!

ReplyDeleteKalejs
1. Learned: Fab@Home enables creation of 3D models.
2. Pressing ?: Is the compliance of the double-dipped model close enough to that of the native porcine aortic root?
3. Presentation: Could you play those 2 videos (in RealPlayer format) for us? I hate RealPlayer too much to bother installing it.
4. Thoughts: I can see now why people have been so obsessed with Fab@Home.
1. The Fab@Home is an effective way to make a silicone replica of the aortic root.
ReplyDelete2. How small can pipette tips be made? What else does Fab@Home do? What are other applications?
3. I would also love to see those 2 videos.
1. By using Fab@Home, we can build flexible, life-size 3D models in quicker and simpler ways than casting techniques.
ReplyDelete2. Is this method inexpensive to the extent that 3D models can be derived from medical imaging of patients in office? Also, would making a model for every patient before surgery greatly increase operation successes more than traditional imaging? (Beyond educational purposes, does this seem to be a practical method for operation planning?)
3. Could you speak to the capacities of Fab@Home? What is it capable of, in general?
Raheel Thobhani
ReplyDeleteKalejs
1. Fab@Home uses 3D fabrication with silicon to make a human aortic root.
2. Are there any other materials that can be used besides silicon? What are some possible ways to reduce the production error?
3.Other applications of the technique. What else can be made?
1.Fab@Home was used to make silicon model of human aortic stem
ReplyDelete2.Why did they use silicon?
3.An overview of Fab@Home
Kevin Qin
ReplyDeleteKalejs
1. The production of 3D models with the Fab@Home.
2. Why was silicon used? Could a material that is more capable of mimicking human tissue be used instead?
3. Would the error in the dimensions of the model have any significant effect on simulations?
Kalejs
ReplyDelete1. A Fab@Home was used to create an aortic root in silicone.
2. So for the twice dipped model, it shrinks when pressure increases from 0 to 80-100 (and still has shrunk at 100-150)? Seems counter-intuitive.
3. How Fab@Home 2.0 is better than 1.0
Lauren Kolski
ReplyDeleteKalejs

1. A new method to create a hollow compliant component that can mimic aortic tissue using a Fab@home single step process
2. The article noted that the uncoated silicone model was unable to withstand physiological pressures, but the coated models could. Do the coated models mimic anatomical and physiological behavior as well as the uncoated ones do? Also, other than it being cheap and available, what particular properties make silicone a good choice for the replication of the aortic root?
3. An overview of the Fab@home process and machine
